JOHN w. Hanna, or nnwnnn, new ufimism To all it' may concern Beit known that I, JO N WL HrArr, a

- {eitizenof the United States, residing at'724, Ridgestreeh'Newark, county of Essex, and

State of New Jersey, have inventedcertainf new and useful Improvements inBowli-ng- Balls with Self-Contained ;Handles,; fully described and representedin the following forming, a part. of the same.

.. eeifioation and the accompanying draw- 10 1 u t he ob ect of the present invention ISitO furnish a bowling ball with a handle which;

maybe drawn outward from thisuriace of the ball to use in throwin the sam and which handle may have suc proportions as 1per'nrhit the fingers when to penetrate within its When inserting the. fingers in theord1- .hel close "to the hand and can be guided? and thrown with certainty; but with handles.

which; afford a grip wholly external to the,

surface ofthe ball, the ball hangs upon the% hand in an unnatural position and cannot be guided and thrown with the same .cer- .tainty.-

constructed so as to permit the fingers of the; hand. toenter a doorway in the side of the;

ball, and thus to hold the ballficlose to the palmofthe hand.

The vention is especiallyap plicableto va hollow; ball having a spherlcal'metallic shell, within which the fixtures, may readily I be arranged for supporting and operatinga door for the handle in the desired manner.

' to permit the insertion of the ers at one edge of the doorway, and the hand-piece which remains within the surface ofthe ball ,isthus crowded laterally so as to contact with such inner surface, if desired, and hang the ball directly upon the hand-piece. V p A spring is provided to retract the handle, and a latch to lock it in plaee'when drawn inwardly, and two or more edges of thefdoorway are beveled and the edge of the door constructed to overlap such bevels, and thus sustain the door firmly upon the ballwhen thrown upon thefioor of the alley. v g

.. If desired, lugs may be extended inwardly from the ends ofthe hand-piece to engage inclinedguide-rodswi-thin theball, so that when the handle is drawn outwardly from the ballitis automaticall- "moved in a lat eral direction, so as to a ord the space for the. handle are not essential to: the myentmfl: v p .-llh invention will be understood by reiterence to theannexed drawing, in which- Figure 1 is a plan; of. the ball looking toward the door; Fig. 2 isa. verticalsection on thecenter line .of Fig. 1, showingonly; the

,1. means for sustaining'the door when the In the present invention, .the handle 1sj ball-is in. use; Fig, 3? is a sectionon line in Fig, 1; Fig. .t-is asection on line Figgand Fig. -5 is a view showing one side 0 the handle exhibiting-the hand- 1 piece which. sustains the ball when throwing the same --Fig. 6 is a section .on line in Fig. l,;with the fingersapp'lied-to the an le @5 31 J The ball is shown with,metallic shell a having 'a coating b'of suitable composition, as hard. rubber, or othersubstance capable of being molded in a plastic state upo th exterior of the'shell. The shell is formed in onefside wvith an oblong doorway having ends c-and edges d, d, and adoor e fitted to moveinto and out of such doorway, with spherical exterior to complete the surface of the ball..

To set the surface of the door flush with the ball and to sustain any vblows to which the door may be subjected when the ball is in use, beveled shoulders 0 are formed upon the-ends of the door, and the endsc of the doorway are correspondingly beveled, thus supporting the door rigidly when the ball is m use.

t v v V the insertion of thehand; but such means of nar. {finger-holes in the ball, the ball is A shank-plate. f is extended inwardly from V one edgeof the door, and a hand-fpiece in the form of a flange g is projected 1' plate upon the same side as the'door, and formed with hollows-or notches g adapted to receive the fingers of the hand. The plate f terms a shank upon the door-piece to move'the hand-piece outward when required. At the opposite ends of the hand-piece, lugs k are extended inwardly and formed with slotted sockets h adapted to slide upon 'guide rods z, which are held-at an angle to *thesurface of the-ball at the-doorway, by shanks j threaded i'nto bosses-k withinthe ball at one side of the doorway.

'The guide-rods slope across the doorway between the opposite sidesof the ball, and their inclination is such that when the sockets k slide upon the guide-rods it moves the doorway oblilpxiely from one side of the doorway toward t e opposite side; the slots 7; in 'the sockets permitting the door and hand-piece to be pulled outwardly until the door can be moved laterally. I A finger-hole p is made in the shell adjacent to the edge 'olof the doorway, and a latch-piece 1" is hinged at its upper end by a screw g', in the side of the finger-hole, and pressed normally towardthe plate 7 by a spring 9-. I

a A notch s is formed in the plate f, with which the end-of the spring-latch q'engages automatically when the handle is retracted into the ball, and the door is thus held firmly flush with the surface of the ball 'when rolling upon the alley.

To draw the handle from the ball, a pocket f -is'pro'vided in the plate fjust below the door-piece, adjacent to the finger-hole p;- so that a finger of one hand can be inserted in the finger-hole and operate first, to push the latch from the notch-s, and se'cond,to engage thepocket 2 to lift the door-andjmoveqit laterally su cient to insert the fingers of the hand beneath thehand-pieceand pull the handle outward. As the hand-piece remains in the shell of the ball, the fingers alsolie directlywithinthe shell, as" shown in Fig. 6, and the ball is thus gripped-as closely by thehand as if the'fingers were inserted ;in the ordinary finger-sockets.

The doorway is so proportioned in practice, as well as thespace between the lugs h,

' that all four fingers of onehand may be in sorted" through one side of the doorway and extended beneath the hand-piece to--lie in the notches f while supporting the-ball. 1 '-The hand-piece is kept from rocking or tipping during the throwing operation, by the long slotted lugs h which are formed with shoulders k to contact with the ends of the bosses at the same time that the plate f contacts with the edge of the doorway, and the handle is thus held firmly during the throwing operation; such contact forming St p for the handle at two diiferentpoints b om the J0, and provided atthe opposite end with hook m adapted to be pulled through a hole n in the periphery of the ball, and to hook over a bridge 'n, adj acent such hole.

To further sustain any'blows that the door may be subjected to when the ballis in use,

a bracket 0 is projected from the interior of the ball beneath the hand-piece'and fitted to contact with the-same, as shown in Fig. 2,

when the handle is retracted; 4

A dowel 0 may be projected from the bracket, to engage a hole u in the hand-piece, to center the same when'retracted.-

It will be understood from theabove description, that the handle comprises a door e connected with an inner handpiece 9 and adapted to move obliquely as it is pulled out of the ball, soas'to permit the insertion of the fingers at one side of the doorway "to engage them with .the under side of the hand-piece, so that the ball hangs directly upon the hand while throwing it. The oblique movement is permitted by the s ace between thddoor-p'iece and the" hand-piece, at one side of the shank or plate f:

The hand-piece g'lies just within the shell when adjusted for use, and the hand of the operator thus extends partly within the shell in gripping the hand-piece, the fingers being held firmly in the'notches g in the/handpieceby the application of the thumb to the outer side of the door, as'shownin Fig; 6.

I The door operates not only to-close the tion of'the surface and thus resists concus iions as effectively as the body itself of the a11.---"

Theffinge'r-hole p which is 'provided'for the ffinger'to release the latch 1- for drawing -out-"thehandle, does not impair the surface of the ball any more than the finger-holes which are often used in such balls for the insertion of the thumb and. finger, and is not in practice any detriment to the operation'of the ball. v

' The bracket 0 is formed,'upon" the side adjacent to the plate f, with a'surface 0 parallel to the plate f when the handle-is retracted, and as the spring in retracting the handle draws it toward such surface, the'plate serves as an efiicient guide to-the movement of the handle as it enters thepball, and brings the door positively into its'workhag! position to close the doorway i n the opening in theball, but, forms a rigid porrolling surface of the ball, as the handle is combined with a door which wholly closes the aperture through which the fingers are inserted.

Having thus set forth the nature of the invention what is claimed herein is:
